If you want to import data from one website to another, there is no dedicated option available in ULP.
A solution may be to use one of the default import solutions provided by WordPress: WordPress Importer.
If you want to import users from a different learning system to ULP, you can do so if those users are WP users. ULP is linked to WP and any user that is added as a WP user will show up in the ULP system.
